To all-idiom it may concern:-

Beitithow'n thatII, JOHN F, Bummer H |1,iitsville, in the county otMadison and State. of Indiana, have, invented a new and useful Improvement in Railroad-Switehes; 'aud Ldohereby' declare that thefoilowing-is a full, clear, and exact description thereof} which will enable others skilled in, the, art to make and use the same, reference being had to the accompanying drawing, 'formingpairt of my invention.

This invention relates. to an improvement on a means-employed for throwing automatically, by the movement of the switch, an ob siruction or scotch across the. rail or rails of atnrn-out toprevent the cars switched on, onisaid turn-om:- from-passing hack on the track,iwhich means-was patented by J acobv, Beachler, assignor to myself, on the 19th-day otJuly, 185 9, 1 wi'tliindescribed invention consistsin i connectingth'e obstruction or scotch with the 4 switch by two cross-rods and. a eT-shaped'le Y ver, arranged in such a manner as to enable the obstruction or .scotch to be' moved or ad'- Jnsted' vwith much less friction than formerly,

the single rod and L-shaped lever used in the previous invention not working'smoothly, and

causing considerable embarrassment and frequently some delay a in operating the switch. a I A A represent the tworails of amain track,

7 -and'B' B the two rails of a turn-out,

[a switch arranged in the usual way, so as to be capable of forming a connection with either track, as may be desired.

U being switch are connected by across-bar, D, theist- .ter being'counected by a link, l)',to which a E, is at The lever E is conone arm, 0, of the' lever E.

d, witha sleeper,'F,

nected-by a fulcrum-pin,

I on'which the-tree or. disengaged end of-the switch rests or works.

" rods cross other, and they connected at their ends. to a bet, E, which is secured by a-central pivot, Ate-one of the.

when the Denis turned in a position at; rightziecvinl ate -B om t "rails, the bar or The two rails of the tached by a pivot, a,

a switch to prevent This bar nearest .rail,"so as tc forma'scotch,' and pre ventcars from passing in a direction toward the switch.

The rods G G'are'attached to opposite ends of the bar H, and

crossed,.it will'be seen that when the switch ,is moved'in. line with the main track the-hubh of th'e-bar'H will be turned over one of the rails'B of the turn-out, and when the switch is-moved in line with the rails B B of the turn-out the bar H will be turned'oif from said rail to a position nearly as shown in red outline in V the drawing hence it will be seen that parallel with it,

when cars are switched off on the turn-out, and the switch moved back in line with the main over one of the rails of'the turn-oat and the carsznrevented from gassing back on the main track,- or sufliciently travel thereon-a contingency which would be liable to occur, especially if the grade be'a descending one toward the switch. 1

B-a connection being made between the two .scotches by" a rod, so that both will move' simultaneously as motion is communicated to. the one havingthe rods G connected to it.

' The oblong slot b in the arm 0 of the lever E- is' necessary in order to compensate for the curvilinear movement of said lever, which 1 would be considerable if the arm 0 were shut.

The hub h m "y, if desired, be coveredwith iudia-ruhber, to avoid concussions when the. mar-.wimel's v come in contact within By this arrangement the scotch H- is ,moved automatieally'from the switch with butlittle friction.

e I do not claim, broadly,"the employment or useof a scotclFoperated automatically from cars from passing on a turn-out uponthe main railsof a track; but

I claimas new and-desire to secure by Let-' ters Patent-i The-operating of the scotch -H auto'mat "ically'from the switch 0 through the medium of the cross-rods G G and T-shaped lever E,

connected with the" sw'itcmsnbsusntially as in consequence of, being rails A A of the tch Ii will be turned ackto interferewiththe I would remark that, if desired or necessary," two scotches may be usedone for each rail,
